I am the family historian for the Jack RITTENHOUSE tree (and his awesome memoir), Charlotte HIGH trees (jointly with the Elmer Freer team, formerly handled by the late Susan Blair), Calvin BRILEY tree (Michigan/California branches), and help check up on minor branches of these family trees: Harry WILSON, Fred Herzog, Schroeder (California branch), Satterthwaite (the late John Satterthwaite was their family historian). I also help update data for the four Livermore, CA cemeteries.
